September 1-10 (Monsoon Tail): The monsoon is typically still active in early September — afternoon rain continuing, the forest saturated and at maximum green density. Similar to late August: excellent morning conditions, afternoon rain. The forest at its most lush. Good but not the clarity peak.
September 11-20 (The Transition): The monsoon typically ends between September 10-20. The transition is visible day by day: the cloud cover reducing, the afternoon rain becoming intermittent rather than daily, the Islamabad valley below becoming visible through clearing air. By September 15-20 on most years: the air clarity is significantly better than August. The Kashmir Point view to the distant ranges re-emerges. September 21-30 (Early October Character): Late September at Bhurban: the atmosphere is now fully post-monsoon — the clarity is approaching October levels. The cedar estate at 10-18°C in the last week of September. The forest still fully green (the deciduous colour has not yet begun), but the clarity of the air and the quality of the light are moving toward the October peak. An excellent week that October's strong bookings don't always reflect.
